Serial No. 231,175.

This invention relates to shuttles and has reference particularly to the means thereinl vide a simple and efficient means of this class whereby the filling may be established in its controlby introduction of the filling laterally of itself into such control, either by hand or automatically.

In the drawings,

Fig. 1 is a plan of a shuttle embodying the invention g Fig. 2 is a side elevation, partly in section; Figs. 3, 4, 5 and 6 are sectional views on lines 3 3, 4 4, 5 5 and 6 6 of Fig. 2; and Fig. 7 is a view of the lay or batten of a loom and the shuttle in front elevation, illustrating a step in the operation of threading the shuttle when performed automatically.

rIhe shuttle body 1 and its `quill or bobbin cavityV 2 (open topV and bottom) with the quill Vor bobbin 3 therein may be the same as usual, as also may be, if the shuttle is to be automatically threaded, the fitting or thread-V ing block 4 housed in the forward part of the.

body andaifordng the longitudinal filling or thread passage 5 (Figs. 5 and 6) and lateral filling-outlet or side delivery eye 6, the longitudinal top slit 7 by which the filling is entered laterally of itself down into the passage,

and the forwardly projecting deflected hornv 8 which retains the filling in said passage once it has entered the same.

In a horizontal plane and each traversing the forward extension 2a of cavity 2 are the parallel pins or guides 9, here fixed at their ends in holes in the shuttle body and adapted to support the filling in bridging relation to the cavity. A lever 10, in the form of a pluritined fork, is fulcrumed at 11 11 in the fitting 4 and in the lateral upstanding wall 14a of a stand or bracket 14 fixed in cavity 2, so that the fulcrum of said lever is longitudinal of the shuttle and its tines or guides 10a project transversely, or substantially parallel with the guides 9; these guides are in vertical planes alternating with those of the guides 9 and they are arched. The fulcrum of said lever 10 is more or less near the bottom and one 9 side of cavity extension 2a, and the guides 10a are of such length that when the lever is tilted to the position shown in Fig. 4 by dotted lines the ends of the tines, whose arching gives them a hook-like form, project above the guides 9 and when the lever is depressed the end of an arm 10b of the lever may encounter the base of stand 14 as a stop. The lever may be normally urged to the latter position (full lines, Fig. 4) by yielding means, such for instance as an elastic rubber strip 12 one end of which is attached to the fulcrum part of said lever and the other to a revoluble pin 12a mounted in the shuttle body and which may be turned to cause the strip to wrap around 0r unwrap from the same to vary the tension of said strip.

If the tension means formed by guides 9 and the spring-pressed tined lever is to be threaded by hand such may be accomplished by elevating the latter to the dotteddine position, placing the filling on the guides 9 as shown in Fig. 4 so that it will be caught by the tines'when they descend, and then releasing the lever, whereupon the filling Will be drawn into the Zig-Zag arrangement A shown in Fig. 2. During weaving the filling is withdrawn from the shuttle and in its travel from the quill cavity or bobbin chamber to the side delivery eye it is deflected over the guidesv9 and under the tines or guides 10a in a zigzag course as indicated in Fig.'2, so that the yielding character vof the tines or guides 10a takes up slack and applies tension to the filling. j

Preferably for elevating lever 10 there is a device here taking the form of a lever 13 fulcrumed on a transverse axis in the st-and, 14, hereinbefore mentioned. One arm 13a of this lever projects forwardly'and underli-es the arm 10?) of lever 10 and the other, 13b, yprojects rearwardly and serves as a finger-piece when the lever 10 is to be manually elevated. This lever 13 may serve as a detent to hold lever 10 in its elevated position, as by its arm 13a being then in position (see dotted lines Fig. 4) to obstruct return or downward movement of lever 10, or in what I term the cocked relation of these parts, the friction between parts 13a and 10b ico being then sufficient to keep the lever 13 elevated.

Vhere the threading is to be automatically performed the lever 13 has an additional arm 130 which projects upwardly and forwardly and is adapted to protrude from the top of the shuttle when the parts 10 and 13 are in cocked position. Assume the loom 15 (Fig. 7) to be of the usual type (as, for example, shown in Patent #540,454) employing a shuttle whose filled quill or bobbin is entered into the quill or bobbin cavity, as 2, by a downwardly moved presser 16 or other actu' ator on the loom, such as the usual transferrer, the quill or bobbin then in the shuttle will be ejected and if the shuttle contains the present improvements the force of the presser or transferrer to introduce the filled quill or bobbin will, through such quill or bobbin and the outgoing empty quill or bobbin (whose tip overlies arm 13b of lever 13-Fig. 2) shift member 13 and consequently member 10 to cocked position, so that the filling (whose end may be previously attached to some part of the loom, as usual) will bridge the cavity and rest on the pins or guides 9 while the tines of member 1() are raised into dotted line position Fig. 4. In the present example, this will occur when the shuttle is in the right-hand shuttle box. Upon the shuttle performing its next flight to the opposite shuttle box 18 the member 10 will fall and the filling, having meanwhile found its way down through slit 7 into passage 5 so as to be caught under the tines of said member 10 when it thus falls, will be held as seen in Fig. 2, extending zigzag around the guides 9 and 10a and controlled by member 10.

The shock incident to the shuttle flight or its picking movement may cause the member 13 to fall and so allow the member 10 to do so, but in any event member 13 will be depressed as it encounters a trip or stop 17 or other suitable actuator on some part 19 of the loom (Fig. 7) before the shuttle is fully boxed at the opposite side of the loom.

In the well known way the filling, on the shuttle next proceeding to the right from the left-hand box, forms in a bight A? (Fig. 2) and thus becomes established in the outlet 6. Sometimes in the use of fittings, such as 4, adapted for the self-threading of the shuttle the filling works back outA of thisA outlet, which of course is positioned at the side of the shuttle next to the cloth. To prevent this I place in the fitting 4 a bent elastic clip 20 (Figs. 2 and 6) having one end 20a wide and the other end a tapered tongue 20?); such ends project rearwardly and the former is held between the fitting l and the bottom of tho housing formed in the shuttle body to receive such fitting while the latter bears against the under side of horn S'near the forward end of passage 5. This clip forms a simple expedient for the purpose in hand, preventing return of the filling from out-let 6 once it has become established therein by its bight forcing its way between the tongue 206 and the under side of horn 8.

From the construction described as one good form or embodiment of the invention it will be noted that on replenishment of filling in the shuttle, the tensioning members will be moved into non-tensioning relation thereby freeing the filling previously in the shuttle that it may be freely withdrawn therefrom by the quill or bobbin as it is ejected from the shuttle during replenishment, and that the filling leading from the incoming quill or bobbin will be placed in position for the tensioning effect of the tensioning members when the tensioning members are again moved relatively into tensioning position.
